WHEEL-TIRE.

Will appear as the nature of the invention is better understood, the invention consists in certain novel features of construction, as hereinafter fully described'and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by l-iketdesignating characters, is illustrated the preferred form of embodiment of the invention capable of carrying the same into practical operation, it being understood-that various changes in the form, proportions, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention within the scope of the appended claims.

In the drawings, Figure 1 is a side elevation, partly in section, and Fig. 2 is an ed ewise view, artly in section, of a vehic ewheel with t e improvements applied. Fig. 3 is a sectional detail illustrating-a modification in the construction. Fi s. 4, 5, 6, and 7 are views similar to Fig. 3, il modifications in the construction. I

The im roved device is designed more arlication to the heavier'c ass of vehicle-whee s, such as automobiles and the like, and for the pur ose of illustration is shown applied to one o the forms of wheels employed upon vehicles of this class, the felly 10,. spokes 11, andhub 12 being'of the usual form.

The improvement comprises one or more annular members 13, encircling the wheel intermediate the rim or folly and formed with overhanging sides 14 15. The improvement further comprises two annular clamp-plates 16 17, bearing upon opposite sides of the wheel and with inwardly-projecting u per edges 18 19 and secured'rigidly to the w eel by. transverse tervals. Between the intermediate member or members 13 and the clamp-plates 16 17 tire-sections 21 are disposed, the tire-sections ustrating other.

clamp-bolts 20 at suitable in.

being of suitable flexible material, such as rubber, and with the inner portions projecting beneath the overhanging portions of the intermediate annular mem clamp members. I

The initial width of the tire members is greater than the space they clamp members, so that after the parts are in position. the setting of the nuts u on the ers and of the.

are to occupy between the intermediate members and the.

clamp-bolts will compress the yielda le tires and hold all the parts firmly together and retainthem in position. The overhanging form of the members 1316, and 17, coacting lower edgesof the tire members, effectual y'prevents any displacement of the parts.

The sides of the members 13 may be formed with the portions next the felly in parallel lines and the outer portions inclined outwardly or diverging to form the re uisite overhang and the inner faces of the 0 ampplates 16 17 correspondingly formed, as

2, or the overhang porformed Without the paralleltions may be I as shown in Figs. 3 to 7, as

sided sections, preferred.

.The' felly 10 is preferably supplied with an encircling band 23, secured inp ace by clam bolts 24 at suitable intervals, and with t e members 1316, and 17 engaging this band, as shown. The intermediate members 13 are preferably movable laterally relative to the folly, so that they ada the clamp-plates and equa im the pressure upon the tire members. By this means the tire members will be subjected to a uniform pressure no matter What differences there may be between them as to thickness, density, or like qualities. In Figs. 4 and 5 another modified form of the construction is shown, consisting in forming the intermediate member 13 integral with a band 25 encircling the supplemental rim 23, as in Fig. 4, or applied directly to the fell 10, as in Fig. 5, the band 25 being prefera 1 slightly less in width than the rim 23 and felly 10. to permit a degree of lateral movement to cause the tire members 21 to move-readily, adapt themselves to the clampplates and intermediate members, and to equalize the pressure upon the tire members in the same manner as when the members-13 are constructed and arranged as shown in Fi s. 2 and 3.

n Fig. 6 a modified construction is shown t themselves towith three-of the tire members 21 and two of the floating intermediate members 13 ar ranged upon the wheel, and in F ig'. 7 is shown a modified arrangement of the parts with three of the tire members and two of'the intermediate members 13 coacting with one of the bands 25, similar to the structure shown in Figs. 4 and 5. In the modified structure shown in Fig. 7 one of the members 13 is slidable upon the band 25, while the other is integral therewith, which arrangement may be employed, if preferred. Thus any number of the relatively small tiremembers ZL may be employed upon a-single wheel-felly, accordparativel small expense and Without disconnecting t e remaimne tire members.

Havin thusides'cri bed the invention, what is claimed i s--' I 1. The combination with a vehicle-wheel of two or more annular members movably disposed relative to the fellyortion of the same and with the 0 posite e ges overhangin annular clam -p ates bearing against the .si es of the whee and with their inner'faces overhanging, means for securing said clamp- .plates to the wheel, and elastic tire members encircling the wheel between said annular members and said clamp-plates and with the side faces projecting beneath the overhanging portions of the clamp-plates and annular members.

2. The combination with a vehicle-wheel of a band encirclin the telly portion of the same, means for etachably securing said band to the felly, two or more annular membersmovably bearing upon said band and with the sides overhanging laterally, annularclamp-plates bearing upon the edges of said band and with their inner facesoverhanging the band, means for securing said clampplates to the band, and elastic tire members bearing upon the band between said annular members and the clamp-plates and formed with the side faces projecting beneath the overhanging portions of said annular memhers and clam -plates. i 3. The com ination with a vehiclewheel of a band encircling the telly and with an annular rib integral therewith and with side faces overhanging the band, annular clampplates bearing against the sides of the wheel and with their inner faces overhanging the band and elastin tire members encircling the wheel between said annular rib and annular clamp-plates and bearing upon said band and with the side faces of the tire members projecting beneath the overhanging portions of the clamp-plates and ribs. s

In testimony that I claimthe foregoing as my own Iv have hereto afiixedmy signature in the resence of two witnesses.
